Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular to a construction method for large-area complex ceiling designs based on BIM technology. Background Technology

[0002] In modern building construction, especially in the decoration projects of large public buildings (such as conference centers, exhibition centers, and stadiums), the construction of complex ceiling designs has always been a challenge in construction technology. These types of ceilings not only require aesthetic appeal but also high precision in construction and complex installation, placing higher demands on construction techniques and material processing.

[0003] Traditional construction methods often rely on manual experience and on-site judgment by technicians, lacking systematicity and precision. This leads to low construction efficiency, difficulty in quality control, and a high error rate. Particularly when dealing with large-area, complex ceiling designs, the lack of effective zoning and transition methods makes adjacent areas prone to cracking due to structural expansion and contraction. Furthermore, cracks easily form at the connection between the ceiling and the wall, and uneven stress on the hangers causes panel cracking, problems that have long plagued construction workers. These issues severely impact construction quality and project progress, increasing rework and repair costs. Therefore, existing technologies urgently need improvement to address these problems. Summary of the Invention

[0004] Therefore, it is necessary to provide a BIM-based construction method for large-area complex ceiling designs that can improve construction accuracy, reduce structural cracks, and enable orderly installation of panels, addressing the aforementioned technical issues.

[0005] Firstly, this application provides a construction method for large-area complex-shaped suspended ceilings based on BIM technology, the method comprising: Obtain architectural structural drawings and ceiling structural drawings, and create a BIM ceiling model based on the architectural structural drawings and ceiling structural drawings; Based on the BIM ceiling model, the large-area complex ceiling is divided into multiple design areas, and adjacent design areas are naturally transitioned by curved process grooves to eliminate cracks caused by structural expansion and contraction. Each shape area is divided into multiple blocks, and the structure of the BIM ceiling model is refined by adding decorative components, equipment installation accessories, and information on connecting screw holes. In the BIM ceiling model, each panel is coded to generate a QR code; The BIM ceiling model and the QR code are loaded into a mobile device to guide installation on the construction site, and orderly installation is achieved based on the QR code of each panel.

[0006] In one embodiment, the process of dividing each shape area into multiple blocks and refining the structure of the BIM ceiling model by adding decorative components, equipment installation accessories, and connecting screw hole information includes: Based on the BIM ceiling model, each shape area is divided into grids, and the overall ceiling is divided into horizontally preset-sized blocks and vertical blocks. The vertical blocks are broken at curved process grooves, light troughs or equipment openings to ensure installation accuracy. In the BIM ceiling model, main control points are set to control the spatial coordinates of the blocks in layers. During installation, coordinate data is extracted from the BIM ceiling model and laid out on site using a total station to achieve precise positioning of the installation position of each panel. The BIM ceiling model is refined by adding decorative components, equipment installation accessories, and information on connecting screw holes.

[0007] In one embodiment, after refining the structure of the BIM ceiling model and adding decorative components, equipment installation accessories, and connecting screw hole information, the method further includes: Based on the BIM ceiling model, the processing parameters of each panel are exported to achieve precise prefabrication in the factory; Pre-embed the hanger connecting nuts and reserve holes for lighting fixtures, sprinklers, and air vents.

[0008] In one embodiment, obtaining the building structure drawings and the ceiling structure drawings, and establishing a BIM ceiling model based on the building structure drawings and the ceiling structure drawings, includes: Obtain architectural and ceiling structure drawings, and establish a preliminary BIM ceiling model; Three-dimensional scanning of the actual building structure and ceiling base layer generates measurement point cloud data; Based on the measured point cloud data, the preliminary BIM ceiling model is modified and adjusted to obtain the final BIM ceiling model.

[0009] In one embodiment, obtaining the building structure drawings and ceiling structure drawings, and establishing a preliminary BIM ceiling model includes: Obtain architectural structural drawings and ceiling structural drawings, and create a main building model in BIM software based on the architectural structural drawings; Based on the main building model, a ceiling model is created according to the ceiling structure drawings. The ceiling model and the main building model are filled with a design transition layer structure model and a suspension rod structure model to form a preliminary BIM ceiling model.

[0010] In one embodiment, the BIM-based construction method for large-area complex ceiling designs further includes: A suspended ceiling device is installed around the perimeter of the ceiling to completely isolate the ceiling from the surrounding walls of the building, creating a suspended state and thus solving the quality problem of cracks easily forming between the ceiling and the walls.

[0011] In one embodiment, the BIM-based construction method for large-area complex ceiling designs further includes: A spring-type energy storage and deformation device is installed at the end of the suspension rod. The elevation and stress of each suspension point are precisely adjusted through the spring-type energy storage and deformation device to release stress and prevent the panel from cracking.

[0012] In one embodiment, the BIM-based construction method for large-area complex ceiling designs further includes: The installation process is optimized through BIM-4D simulation, and the spatial relationship between the panels and pipelines is analyzed to avoid conflicts.

[0013] As can be seen from the above, the large-area complex ceiling construction method based on BIM technology provided in this application solves the problems of insufficient precision, easy cracking and chaotic installation in traditional construction by establishing a BIM ceiling model to divide the shape area, encode the panels and guide the installation. It has the advantages of improving construction precision, reducing structural cracks and realizing orderly installation of panels. Attached Figure Description

[0015] This invention provides a method for constructing large-area, complex-shaped suspended ceilings based on BIM technology.

[0016] The embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While some embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the accompanying drawings and embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0017] In the description of the embodiments disclosed in this invention, the term "comprising" and similar terms should be understood as open-ended inclusion, i.e., "including but not limited to". The term "based on" should be understood as "at least partially based on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The terms "first", "second", etc., may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0018] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 One embodiment of the construction method for large-area complex ceiling designs based on BIM technology in this invention includes: S100: Obtain architectural structural drawings and ceiling structural drawings, and create a BIM ceiling model based on the architectural structural drawings and ceiling structural drawings.

[0019] Among them, the BIM ceiling model refers to a digital three-dimensional model that integrates the main structure of the building and the ceiling design. It can be created using Revit software and includes spatial relationship data such as the transfer layer structure and the distribution of hangers, providing a precise coordinate reference for construction.

[0020] Specifically, first, obtain the architectural structural drawings and ceiling structural drawings. The architectural structural drawings include floor plans, structural beam diagrams, and MEP (Mechanical, Electrical, and Plumbing) drawings, used to clarify the building's geometric information and positioning data. The ceiling structural drawings involve details such as the ceiling joists, base layer, and accessories, requiring a clear understanding of the ceiling's construction, dimensions, and installation method. Then, based on these drawings, use BIM software (such as Revit) to create a model. Specifically, create a new project in Revit, select a suitable project template (such as architectural, structural, or MEP), and import the architectural and ceiling structural drawings into Revit as a reference for modeling. Create grid lines and elevations in Revit as a reference framework for modeling, and arrange building components (such as walls, columns, beams, and slabs) according to the information in the drawings. Utilize Revit's parametric capabilities to adjust the dimensions, materials, and positions of the components, ultimately obtaining a BIM ceiling model.

[0021] S200, based on the BIM ceiling model, divides large-area complex ceiling shapes into multiple shape areas. Adjacent shape areas are naturally transitioned through curved process grooves to eliminate cracks caused by structural expansion and contraction.

[0022] Specifically, based on BIM technology, large-area, complex ceiling designs are divided into zones using a BIM ceiling model. Combining mechanical and aesthetic analysis, the ceiling is divided into multiple design areas. The BIM ceiling model also supports parametric design, allowing complex shapes to be broken down into prefabricated panels for easier processing and installation. Curved process grooves are precisely designed within the BIM ceiling model. Through BIM modeling and stress analysis, the curvature and arrangement of these grooves are optimized to achieve a natural transition between adjacent design areas, reduce structural stress concentration, and eliminate cracks caused by structural expansion and contraction.

[0023] In this embodiment, the BIM ceiling model is used to divide the design area and set curved process grooves, which effectively solves the problem of cracks caused by structural expansion and contraction deformation in large-area complex ceilings, and improves the construction quality and service life of the ceiling.

[0024] S300 divides each shape area into multiple blocks and refines the structure of the BIM ceiling model, adding decorative components, equipment installation accessories, and connection screw hole information.

[0025] Specifically, based on the BIM ceiling model, large-area complex ceiling designs are divided into multiple design areas, and each design area is further subdivided into blocks. Each block corresponds to a generateable panel, and each block is a curved quadrilateral. The corner coordinates of each block are marked to facilitate subsequent processing and installation. Each design area undergoes detailed design to achieve refined structural details. Specifically, the BIM ceiling model is refined, adding information on decorative components, equipment installation accessories, and connecting screw holes. Decorative components include GRG panel finishes, lighting fixtures, fire-fighting equipment, etc., and are detailed in the BIM ceiling model to ensure accuracy during construction. Equipment installation accessories include the installation locations and embedded parts information for equipment such as lighting fixtures, fire sprinklers, and air conditioning vents, which are marked in advance in the BIM ceiling model for easy factory prefabrication and on-site installation. Connecting screw hole information is added to the model to facilitate positioning during processing and installation.

[0026] In this embodiment, in the ceiling decoration construction based on BIM technology, the ceiling design area can be divided to achieve refined management of complex shapes; by refining the structure of the BIM ceiling model and adding decorative components, equipment installation accessories and connecting screw hole information, the accuracy and practicality of the model can be improved, which helps to realize the industrialized construction mode of "factory prefabrication and on-site installation" and improve construction efficiency and quality.

[0027] In S400, each panel in the BIM ceiling model is coded to generate a QR code.

[0028] Specifically, a unique identifier is generated for each panel using a QR code, establishing a one-to-one correspondence with the BIM ceiling model. The QR code serves as a physical carrier, embedding the coded information into the panel. Scanning the QR code allows users to view the panel's geometric, processing, and material information, enabling real-time querying and updates.

[0029] In this embodiment, the QR code encoding of the board material facilitates processing, transportation, and on-site installation, thereby improving construction and management efficiency.

[0030] The S500 loads the BIM ceiling model and QR codes into mobile devices to guide installation on the construction site using the BIM ceiling model and to achieve orderly installation based on the QR codes of each panel.

[0031] Specifically, installers need to load the BIM ceiling model and QR codes into mobile devices (such as tablets or mobile phones). On the construction site, these mobile devices are used to load the BIM ceiling model, providing efficient and intuitive visual guidance for the construction process. During installation, each panel must be installed systematically according to the QR code used during manufacturing. The inspection status in the BIM model is then checked using the mobile device. Specifically, each panel has a QR code label. During installation, the installer scans the QR code, and the mobile device automatically locates the corresponding component in the BIM ceiling model, highlighting its position and installation requirements (such as direction and angle). After scanning, the panel's number, dimensions, manufacturer, installation parameters (such as interface information), and quality inspection standards can be obtained, replacing traditional drawing consultation. After installation, scanning the QR code updates the "installation complete" status of the component in the model and compares it with the inspection standards to ensure quality compliance.

[0032] In this embodiment, loading the BIM ceiling model and QR code into a mobile device enables the on-site application of the BIM model, precise positioning of components, and orderly installation, significantly improving construction efficiency, quality, and management accuracy.

[0033] Compared with existing technologies, traditional construction relies on two-dimensional drawings and manual measurement. This solution uses BIM ceiling models to achieve three-dimensional visualization guidance, improving installation positioning accuracy. Existing processes use rigid splicing, while this solution uses curved process grooves to form a flexible transition zone, eliminating the conditions for crack formation. Traditional material management relies on paper lists, while this solution uses QR codes to achieve full life-cycle tracking of components, reducing the misinstallation rate. Through the above technical solutions, this application effectively solves the core problems in the construction of large-area complex ceilings: BIM ceiling model data integration avoids design and construction deviations, curved process groove design suppresses structural deformation and cracks, and the QR code coding system realizes precise component management.

[0034] In one embodiment, such as Figure 2 As shown, S300 includes: S320, based on the BIM ceiling model, divides each shape area into a grid, dividing the overall ceiling into horizontally preset-sized blocks and vertical blocks; S340 sets the main control points in the BIM ceiling model, controls the spatial coordinates of the blocks in layers, and extracts the coordinate data from the BIM ceiling model during installation. It then uses a total station to lay out the layout on site to achieve precise positioning of the installation position of each panel. S360 refines the structure of the BIM ceiling model, adding decorative components, equipment installation accessories, and information on connecting screw holes.

[0035] Specifically, based on the BIM model, each decorative area is divided into grids, with the overall ceiling divided into horizontal blocks of 1200-1500mm. Vertical grids are broken at curves, light troughs, or equipment openings to avoid joints at weak points and to facilitate on-site verification of elevation and position. Then, master control points are set in the BIM model to control the spatial coordinates (e.g., XYZ axis positions) of each block hierarchically. For example, primary control points locate the connection between the overall ceiling and the main structure; secondary control points locate the boundaries of each decorative area; and tertiary control points refine the installation points of individual panels. During installation, coordinate data is extracted from the BIM model and laid out on-site using a total station to ensure that the positional error of each panel is ≤2mm. The total station is a high-precision measuring device capable of angle measurement, distance measurement, and coordinate positioning. Based on the coordinate data in the BIM ceiling model, the total station accurately projects the design points onto the construction site, achieving a "what you see is what you get" layout effect. Secondly, the BIM ceiling model is refined by adding decorative components, equipment installation accessories, and information on connecting screw holes.

[0036] In this embodiment, segmentation reduces construction complexity, improves installation accuracy, and creates conditions for factory prefabrication. Extracting coordinate data from the BIM ceiling model and performing on-site layout using a total station avoids overall deformation caused by accumulated errors in traditional construction, enabling precise shaping of complex curved surfaces. In one embodiment, after refining the structure of the BIM ceiling model and adding decorative components, equipment installation accessories, and connection screw hole information, the method further includes: Processing parameters for each panel are exported from the BIM ceiling model to achieve precise prefabrication in the factory; pre-embedded hanger connecting nuts are used, and holes for lighting fixtures, sprinklers, and air vents are reserved.

[0037] Specifically, based on the BIM ceiling model, processing parameters for each panel can be exported, such as curve curvature and equipment hole locations, providing detailed data support for prefabrication in the factory. For example, the point coordinate information extracted from the BIM model can guide the factory's production machines to manufacture with precision, ensuring that the dimensions and specifications of each component are consistent with the design. Simultaneously, pre-embedded hanger connecting nuts and reserved holes for lighting fixtures, sprinklers, and air vents provide interfaces for the subsequent installation of hangers, lighting fixtures, sprinklers, and other equipment, thereby improving construction efficiency and quality.

[0038] In this embodiment, the problem of misalignment of panels caused by manual measurement errors in traditional construction is effectively solved, material loss caused by on-site drilling is avoided, equipment installation rework caused by hole position deviation is significantly reduced, and high-precision prefabrication and rapid installation of complex ceiling components are achieved.

[0039] In one embodiment, obtaining architectural structural drawings and ceiling structural drawings, and establishing a BIM ceiling model based on the architectural structural drawings and ceiling structural drawings includes: Obtain architectural and ceiling structure drawings to create a preliminary BIM ceiling model; perform 3D scanning of the actual building structure and ceiling base to generate measurement point cloud data; modify and adjust the preliminary BIM ceiling model based on the measurement point cloud data to obtain the final BIM ceiling model.

[0040] Specifically, the process begins by importing architectural structural drawings into BIM software to generate a main building model, which is then overlaid with ceiling structural drawings to form a preliminary BIM ceiling model. Since actual construction errors may cause discrepancies between the drawings and the site, precise measurements of the building structure (e.g., floor height, beam locations) and the ceiling substrate (e.g., embedded parts, hanger locations) are necessary. Specifically, a 3D scan of the actual building structure and ceiling substrate generates measurement point cloud data. This data is then input into the BIM software, and a coordinate transformation algorithm is used to match the measurement point cloud data with the model coordinate system, automatically identifying areas of difference between the dimensions marked on the drawings and the measured data. For areas where the difference exceeds the allowable error threshold, key parameters such as the ceiling joist spacing and the length of the transition layer hangers are adjusted using a parametric approach to ensure topological matching between the model's curved surface and the actual building's spatial curved surface. In the final generated BIM ceiling model, the 3D coordinates of each hanger connection point are consistent with the on-site measured data.

[0041] In one embodiment, obtaining building structure drawings and ceiling structure drawings, and establishing a preliminary BIM ceiling model includes: Obtain architectural structural drawings and ceiling structural drawings, and create a main building model in BIM software based on the architectural structural drawings; based on the main building model, create a ceiling model based on the ceiling structural drawings, and fill the space between the ceiling model and the main building model with design transition layer structural models and hanger structural models to form a preliminary BIM ceiling model.

[0042] Specifically, the main building model first establishes a spatial coordinate system based on the building structure drawings, using the building axis grid and elevation information. A precise building framework is then formed through 3D modeling of beams, columns, walls, and panels. The ceiling model is modeled within this coordinate system to ensure spatial consistency with the main building model. The transfer layer structural model accurately simulates the connection between the main building and the ceiling by creating a 3D solid model of the steel frame transfer layer. The hanger structure model uses a parametric approach to construct adjustable hanger components, with the installation angle and length of each hanger automatically calculated from the BIM model coordinates. During the 3D model assembly, the transfer layer structural model serves as an intermediate layer between the main building model and the ceiling model, while the hanger structure model connects the transfer layer and the ceiling, forming a complete spatial assembly system. In this embodiment, by directly creating a building main model from the architectural structural drawings and integrating a ceiling model on this basis, the risk of errors from repeated manual modeling can be reduced, and the precise positioning of components can be ensured. Filling the space between the ceiling model and the building main model with a design conversion layer structural model and a hanger structural model to form a complete BIM ceiling model helps to detect and optimize gap relationships and avoid construction conflicts.

[0043] In one embodiment, the construction method for large-area, complex-shaped suspended ceilings based on BIM technology also includes: A suspended ceiling device is installed around the perimeter of the ceiling to completely isolate the ceiling from the surrounding walls, creating a suspended state and thus solving the quality problem of cracks easily forming between the ceiling and the walls.

[0044] Specifically, due to the characteristics of large-space buildings such as height, span, area, and complex shape, ceiling deformation and cracks are prone to occur, affecting the construction effect. Cracks are particularly severe at the junction of the ceiling and walls, where different materials and structural rigidities cause the transition. Installing a suspended ceiling device with panels around the perimeter completely isolates the ceiling from the surrounding walls, creating a "floating" state. This effectively solves the common quality problem of cracks easily forming between the ceiling and walls. Simultaneously, using shock-absorbing connectors to connect the walls and ceiling, and providing appropriate horizontal prestress, prevents ceiling swaying. Using decorative lighting troughs to naturally transition between the walls and ceiling maintains the overall harmony and aesthetics of the ceiling design.

[0045] In one embodiment, the construction method for large-area, complex-shaped suspended ceilings based on BIM technology also includes: A spring-type energy storage and deformation device is installed at the end of the suspension rod. The elevation and stress of each suspension point are precisely adjusted through the spring-type energy storage and deformation device to release stress and prevent the panel from cracking.

[0046] Specifically, during the construction of large-area suspended ceilings in buildings, factors such as deformation of the main structure and the joists may cause additional stress on the ceiling panels, leading to significant displacement and deformation at the hanger points. This can result in cracks in the panels, affecting the aesthetics. Installing spring-type energy-storing deformation devices at the ends of the hangers allows for precise adjustment of the elevation and stress at each hanger point, releasing stress, eliminating additional stress on the panel system, and thus preventing cracking.

[0047] In this embodiment, the spring-type energy storage deformation device, by releasing the additional stress during the installation and use of the ceiling, combined with the suspended ceiling technology, completely solves the problem of cracks at the connection between the wall and the ceiling.

[0048] In one embodiment, the construction method for large-area, complex-shaped suspended ceilings based on BIM technology also includes: The installation process is optimized through BIM-4D simulation, and the spatial relationship between the panels and pipelines is analyzed to avoid conflicts.

[0049] BIM-4D simulation refers to a dynamic simulation technology that combines a three-dimensional building information model with a time dimension. Specifically, it can be implemented using software such as Navisworks and Synchro. By importing construction schedule data, a four-dimensional visualization model is generated to analyze the space occupancy at different construction stages.

[0050] Specifically, during the construction preparation phase, the BIM-4D model is loaded with pipeline layout data and ceiling panel information, simulating different construction scenarios along a timeline. Based on the BIM-4D simulation results, the installation sequence of ceiling panels and equipment pipelines is adjusted. This can be achieved by adjusting the logical relationships between construction nodes or dividing the work into phased construction areas, thereby avoiding spatial interference caused by overlapping operations. For example, when the installation schedule of ventilation ducts overlaps with the ceiling panel installation plan, the system automatically detects spatial collision areas between the two at specific construction nodes. The construction team adjusts pipeline routing or ceiling panel dimensions based on conflict reports and verifies the feasibility of the adjustments in the model.

[0051] In one embodiment, such as Figure 3 As shown, a construction device for large-area complex ceiling designs based on BIM technology is provided, including: a model building module 10, a design area division module 20, an area block division module 30, a panel coding module 40, and a QR code loading module 50, wherein: Model building module 10 is used to acquire building structure drawings and ceiling structure drawings, and to build a BIM ceiling model based on the building structure drawings and ceiling structure drawings; The styling area division module 20 is used to divide a large-area complex styling ceiling into multiple styling areas based on the BIM ceiling model. Adjacent styling areas are naturally transitioned through curved process grooves to eliminate cracks caused by structural expansion and contraction. The area segmentation module 30 is used to divide each shape area into multiple segments, and to refine the structure of the BIM ceiling model, adding decorative components, equipment installation accessories and connection screw hole information. The panel coding module 40 is used to code each panel in the BIM ceiling model and generate a QR code. The QR code loading module 50 is used to load the BIM ceiling model and QR code into the mobile device so that the BIM ceiling model can be used to guide the installation on the construction site and to achieve orderly installation based on the QR code of each panel.

[0052] In one embodiment, the area segmentation module 30 is also used to divide each shape area into grids based on the BIM ceiling model, dividing the overall ceiling into horizontally preset-sized blocks and vertical blocks. The vertical blocks are broken at curved process grooves, light troughs, or equipment openings to ensure installation accuracy. The module sets master control points in the BIM ceiling model to control the spatial coordinates of the blocks hierarchically. During installation, the module extracts coordinate data from the BIM ceiling model and performs on-site layout using a total station to achieve precise positioning of the installation position of each panel. The module also refines the structure of the BIM ceiling model by adding decorative components, equipment installation accessories, and information on connecting screw holes.

[0053] In one embodiment, the BIM-based construction device for large-area complex ceiling structures also includes a prefabrication module, which is used to export the processing parameters of each panel based on the BIM ceiling model to achieve precise prefabrication in the factory; pre-embedded hanger connecting nuts, and reserved holes for lighting fixtures, sprinklers, and air vents.

[0054] In one embodiment, the model building module 10 is also used to acquire building structure drawings and ceiling structure drawings, establish a preliminary BIM ceiling model; perform three-dimensional scanning of the actual building structure and ceiling base to generate measurement point cloud data; and modify and adjust the preliminary BIM ceiling model based on the measurement point cloud data to obtain the final BIM ceiling model.

[0055] In one embodiment, the model building module 10 is also used to acquire building structure drawings and ceiling structure drawings, and to build a main building model in BIM software based on the building structure drawings; and to build a ceiling model based on the ceiling structure drawings, wherein the ceiling model and the main building model are filled with a design conversion layer structure model and a hanger structure model to form a preliminary BIM ceiling model.

[0056] In one embodiment, the BIM-based construction device for large-area complex ceiling designs further includes a suspended ceiling device setting module, used to set suspended ceiling devices around the perimeter of the ceiling. These suspended ceiling devices completely isolate the ceiling from the surrounding walls, creating a suspended state, thus addressing the quality issue of cracks easily forming between the ceiling and the walls. In one embodiment, the BIM-based construction device for large-area complex ceiling structures also includes a spring-type energy storage and deformation device installation module, which is used to install a spring-type energy storage and deformation device at the end of the suspension rod. The spring-type energy storage and deformation device precisely adjusts the elevation and stress of each suspension point to release stress and prevent panel cracking.

[0057] In one embodiment, the BIM-based construction device for large-area complex ceiling structures also includes a spatial relationship analysis module, which is used to optimize the installation process through BIM-4D simulation, analyze the spatial relationship between the panels and pipelines, and avoid conflicts.

[0058] In one embodiment, this application discloses a computer device including a memory and a processor. The memory stores a computer program that can run on the processor. When the processor loads the computer program, it executes a method for constructing a large-area complex ceiling based on BIM technology as described in the above embodiment.
